No, unfortunately the system has distributed the data incorrectly and wired headphones have been used instead of wired charging. Thank you for pointing this out, we were able to correct the error.
According to the dealer, 5 hours are for music playback time and 2.5 hours for talk time.
I myself use the Buds for listening to music and making calls with my mobile and PC. The Buds connect without any problems and last for several hours. They also sound good.
